.To all whom it may concern.-

Be it known that I, TBEODOR LANGER, a subject of the Emperor ofAustria-Hungary, residing at Vienna, Austria-Hungary, have inventedcertain new and useful Improvements in Smoke-Consuming Apparatus forFurnaces, (for which I have obtained Austria- Hungarian Letters PatentXLIII, No. 3,693, XXVII, No. 3,629, dated September 25, 1893; GermanLetters Patent No. 71,876, dated August 30, 1892; Swiss Letters PatentNo. 5,906, dated August 30, 1892; French Letters Patent No. 224,044,dated August 30, 1892; Belgian Letters Patent No. 101,186, dated August30, 1892; English Letters Patent No. 15,542, dated Aug. 30, 1892;Italian Letters Patent No. 32,57 6, dated August 30, 1892, and SpanishLetters Patent No.- 13,726, dated August 30, 1892,) of which thefollowing is a specification.

My invention relates to smoke-consuming apparatus for boiler-furnaces ingeneral, and forlocomotive-boilers in particular.

The principal objects of my invention are, first, to provide anefficient and comparatively inexpensive smoke-consuming apparatusadapted to be connected to the furnace of a boiler, whether said boileris employed in conjunction with a stationary, locomotive, or marineengine; second, to provide in such an apparatus a regulator forcontrolling the inlet of air into the furnace above the grate and theadmission of steam,in conjunction with said air, to assist in theconsumption of the products Within said furnace; third, to provide insuch an apparatus an air-regulating device adapted to be set inoperation by the opening of the furnace-door and to control the gradualclosing of said door, and, fourth, to provide in such an apparatus anair-regulating device adapted to be set in operation by the opening ofthe furnace-door, alaterallyadjustable and vertically-movable catchcontrolled in its vertical movement by said airregulating device, and ashaft controlling the furnace-door and connected with the air-regulating device by suitable mechanism, the catch controlling the movement ofsaid shaft during the closing of the furnace-door.

My invention consists in the combination and arrangement of partswhereby the abovedescribed objects are attained, and my inventionfurther consists of a smoke-consuming apparatus for furnaces,substantially as hereinafter described and claimed.

improved apparatus as it is applied to a locomotive-engine boiler. Itis, however, to be understood that the invention is equally applicableto all forms of boilers, either for stationary, locomotive, or marineservice.

The nature and general featuresof my in vention will be more, fullyunderstood from with the accompanying drawings, forming part hereof, inwhichin front elevation attached to the furnacedoor of alocomotive-boiler. Fig. 2 is a top or plan view of the same; and Fig. 3is an end elevation, partly sectioned, of Fig. 1, the airregulatingdevice being removed.

Referring to the drawings, 1 represents the air-regulating apparatus,consisting of a cataract, as shown, or of a clock-work operating in sucha manner as that a bracket 3 of the of connection 2, will within acertain predetermined time perform a certain stroke. This bracket 3, forsake of brevity, is hereinafter designated as the operator, and thisoperator 3 is connected-with the shaft 6 of a furnace-door 4 in such amanner that when the door is opened the cataract 1 is set in operationand serves through the shaft 6 to gradually return or close thefurnace-door.

In the construction represented in the drawings an air regulator orcataract is employed,

matter of an application for a patent filed January 19, 1893, underSerial No. 458,990. In this apparatus a piston is made to ascend by theopening movement of the furnacedoor, whereby air-is forced from or drawninto the apparatus through a relief-valve 35, while when thefurnace-door is to be closed the piston of the cataract to which theoperator 3 is connected will descend in proportion Figure 1 illustratesmy improved apparatus a same, carrying an arm, eye, or other means theconstruction of which is made the subject In the accompanying drawingsis shown my the following description, taken in connection to the airadmitted through a regulating-screw 33 into the apparatus.

In the application for Letters Patent filed January 19, 1893, Serial No.458,989, of which the present application is a division, is describedmeans or mechanism whereby the return of the piston will through theoperatorarm close gradually a series of slides or registers in thefurnace-door, and in the present application is described and shownmeans and mechanism for controlling the closing of the furnace-dooritself by means of the cataract 1 and its operator 3, such apparatusbeing especially suited for boiler-furnaces in which space is limited.

A catch or stop 5 is adj ustably carried by a turning screw or worm 37,which by preference is journaled in the supporting-frame of theair-regulating apparatus 1. Upon the spindle of this screw 37 is placeda loose sleeve 38, provided with a grooved pulley 39 and a crank-pin'40.The sleeve 38 is guided in an eye 36, connected with the supportingframeof the cataract. On the same side of the crank-pin 40 a lever 41 and itscounterweight 42 is secured to the spindle of the screw 37. Thecrank-pin 40 is connected with the operator 3 of the cataract l by meansof a rod 9. When the furnace-door 4 is opened the grooved pulley 43 ofthe shaft 6 of said door causes the pulley 39 of the sleeve 38 to rotateby means of a connecting chain or belt,

(not shown,) whereby the operator 3 of the cat-- aract, which isconnected to the crank-pin 40, as before explained, is raised. Thecrankpin 40 and the lever 41, attached to the spindle 37, are eachprovided with lugs or stops 22 and 22, respectively, between which awedge 23 may be pushed. According to the position of this wedge betweenthe stops 22 and 22, more or less of the movement of the cataract willbe imparted to the screw 37, and in consequence the catch 5', operatedby said screw 37, will receive more or less movement therewith. A latch5 carried by the shaft 6, drops over the catch 5 as the furnacedoor isbeing closed, and as a consequence, after firing, the-furnace-door willremain in a more or less open position, and will be closed gradually ata fixed time by the cataract l, as the weight 42 of the lever 41descends.

As a matter of course the wedge 23 may be shifted by hand, or it may beconnected with the operating lever ot' the steam entrance valve, so thatthe adjustment for the phases of artificial and natural draft will beeffected automatically.

In certain cases-as, forinstance, in stationary engines where anadjustment during the working of the engine is not required-the wedge 23may be dispensed with and the grooved pulley 30, crank-pin 40, and screw37 may be rigidly connected.

Having thus described the nature and objects of my invention, what Iclaimas new, and desire to secure by Letters Patent, is-

1. In a smoke consuming apparatus, an air regulating device of thecharacter described, and the operator arm thereof, in combination with alaterally adjustable catch adapted to be vertically moved by saidoperator-arm and with the furnace-door, a shaft adapted to open andclose the same and mechanism connecting said shaft with said operatorarm of said air regulator, all arranged so that when said furnace dooris opened, the air regulator is set into operation through the operatorarm and the catch adapted to be raised to lock the shaft of the door inopen position, and said catch thereafter withdrawn gradually from saidshaft by said operator-arm to allow said door to gradually close,substantially as set forth.

2. The combination in a smoke consuming apparatus, of the air regulatorand its operator arm, a vertically adjustable catch secu red to said armand a screw adjustment for laterally moving said catch with thefurnace-door and its shaft and connections between said operator-arm,thelateral adjusting device and said shaft for operatingsaid lateraladjusting device and said operator arm, whereby when said door is openedsaid catch is elevated to' retain the shaft by said operator-arm, saidoperator-arm controlled by said regulator to gradually withdraw saidcatch from said shaft and said catch graduallymoved in a lateraldirection to permit of the gradual closing of said furnace-door throughits shaft, substantially as and for the purposes set forth.

3. In a smoke consuming apparatus, the combination of an air regulatorof the character described, its operator-arm and a catch adapted to bevertically moved thereby, with a furnace-door and its rotating shaft,means for operating said shaft by said operator-arm, means,substantially as described, controlled by said operator-arm forlaterally moving said catch and means controlled by said operatorarm forpartially or entirely transmitting the movement of said operator-arm tothe shaft of said door to control the extent of opening thereof, allarranged so that when said door is opened said operator-arm is adaptedto control the vertical and lateral movement of said catch and of theclosing of said door, and said door adapted to be controlled by said armas to the extent of its opening movement, substantially as and for thepurposes set forth.

In testimony whereof I have hereunto set my signature in the presence oftwo subscribing witnesses.
